T 0 all whom it may concern.

Be it known. that I, JAMns SHANNON, a. subject of the King of GreatBritain and Ireland, residing at 37 Marquess Road, Canonbury, in theadministrative county of London, England, have invented certain newanduseful Improvements in Cooking Stoves, of which the following is aspecification.

This invention relates to cooking stoves, and has for its obj eottoenable stoves adapted to burn coal and the like to be easily andreadily converted into oil burning stoves.

With this and other ob ects 1n view the lnventlon comprises the variousnovel features of construction, combination and ar- I converted cooking.a line 2-2 ofFigl,

rangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended. vt

.In the accompanying drawings in which similar parts are denoted by likecharacters of reference Fig. 1 is a view in. front elevation of k stovefitted with av single oil vapour burner. v v

Fig. 2 is a view in transverse section on Figs. 8 and 4 are views inplan of an adjustable heat, retaining plate or slab for the bottom ofthe grate, the former showing its adaptation to grates of asinall sizeand the latter to grates ofala'rger' size.

-5. is a View 'n side elevation of one of the elementsof said plateorslab.

Figs. 6 and T are views in end an'd side elevation respectively of oneof the fillingin or gap pieces for use with the adjustable plate orslab, v i v Figs, 8 and '9 are views in elevation an plan respectivelyof a detachable or hollow cone or bellrshape'd grid for the heat retaining plate or slab.

be located in that part of therange'under I the grate usually occ upi'edby the ash pan.

Cooperating with the burner is the usual fuel ta'nk2 whichis providedwithhieans for creating pressure therein and is con-.

nected to the vapourizer by the pipe 3. on

a metallic frame 4' adapted to fit injth'e grate in the place occupiedby the fire bars is placed a. heat retaining plate or slab of fire brickor "othersuitable material which has a suitably slia 1){ed' perforation6, and on the upper side of said plate orslab j above said perforationis formed or mounted Q .70 saidgrid are placed a number of thejo'rdisnary heat retaining-balls or blocjks-9r The perforation 6 in heatretaining plate or slab is so shaped and located as to. substantially a.cone-shaped gridj8. Around jan'dj above coincide with the "shape andposition "of the head ofthe burneir. u

In order to facilitate "the [fitting of; the; Y heat retaining plateorlslab 5 in rang'es'haw ing grates of "different sizes said plateforslab may be Ii llClG lIl two orl more pieces,

the preferred construction to [make it in four sections of similar'shap'e a-nd size which when ljaicl to,' g"etl 1'erwill'form' a slabwhich will fillthe bottom of agi ate of minimum size shown in Fig. 3 andwhich. can be sp'read to form plate "or slab which-willfit a grate of alarger-size."

by the use of four filling-in or'gap'piec'es 7 adapted to occupy thespacesjbetween thfe four sections of the plate or slab asjshofwniII FigY. v i.

In order to support the filling-inp in relation to the seotions'of thepleat-rslab they are made of a T shape cross section the vertical partsbeing adapted WVhen. more than one oil 7 burner orl'a with a pluralityof perforations 6 as shown as shown inFigs. 3, 4,10 and 11 saidgrid ismade as a separate element as shown in Figs. 8, 9 and 12.

The front of the space below the grate of the stove is closed byasuitably shaped, plate e in- Figs. 10 and, 11 and when the plate or slab5 is made in one piece, the grid 8jispreferably made integral with samebut when said plate'or slab is made insections i to fit in the spaces"between the. adjacent sections of the, plate or slab and the h'o ri Izontal parts to rest in the tops ofs'aidt j'secj 'tions'v burner with apluralityof bni iier heads is employedtheplate or "slab 5'is provided 10for the purpose of enclosing the burner and protecting same fromdraughts. This plate can be conveniently suspended from the lower barof'the front of the grate and is provided with a slot 10 to permit ofthe passage of the fuel and induction pipes 3 and 1", and with one ormore adjustable orifices 11 to permit of the adjustmentof the amount ofair passing to the burner head.

- cated above the opening in the heat retaining plate, and a pluralityof heat retaining balls located around and over said grid.

2. The combination with a cooking stove having a grate adapted to burncoal, of an oil vapour burner adapted to be placed in.

the space in the stove under the grate usually occupied by the dust pan,a perforated heat retaining plate adapted to fit in the bottom ofthegrate, a hollow cone-shaped grid located above the opening in theheat retaining plate, and a plurality of heat retaining balls locatedaround and over said grid, and a plate adapted to close the space belowthe plate in which the vapour-burner is located said plate beingprovided with a slot for the passage of the fuel and induction pipes.

3. The combination with a cooking stove having a grate adapted to burncoal, of an oil vapour burner of a size adapted to be placed in thespace inthe stove under the grate usually occupied by the dust pan, aperforated heat retaining plate adapted to fit in the bottom of thegrate, ahollow coneshaped grid located above the opening in v the heatretaining plate, a plurality of heat retaining balls located around andover said grid, and a plate adapted to close the space below the gratein which the vapour burner is located said plate beingprovided with aslot for the passage of the fuel and induction pipes and with adjustableauxiliary air inlets.

, 4, In combination with a cooking stove having a grate adapted to burncoal, an oil vapour burner adapted to be placed in the space in thestove under the grate usually occupied by the dust pan, a sectionalperforated heat retaining plate adapted to fitin the bottom of thegrate, a bell-shaped grid adapted to fit over the opening in the heatretaining plate, means for varying the size of said plate, and aplurality of heat retaining blocks located around and over said grid.

5. In combination with a cooking stove having a grate adapted to burncoal, an oil vapour burner adapted to be placed in the space in thestove under the grate usually occupied by the dust pan, a sectionalperforat-ed heat retaining plate adapted to fit in the bottom of thegrate, a hollowconeshaped grid adaptedto it over the opening I on theheat retaining plate, means for varying the size of said plate, aplurality of heat retaining balls located around and over said coactwith said sectional heat retaining plate, a plurality of heat retainingblocks lo- .cated around and over said grid, and aplate adapted to closethe space below the grate in which the oil burner is located.

7 For the conversion of a stove adapted to be heated by a coal fire intoa stove adapt ed to be heated by an oil burner, a plate of fire-brick orlike heat retaining material for replacing the fire bars forming thebottom of the grate, said plate having a central perforation and ahollowcone-shaped grid located abovesaid perforation.

8. For the conversion of a stove adapted to be heated by a coal fireinto one adapted to be heated by an oil burner, an adjustable perforatedplate of fire-brick or like heat re taining material adapted to take'theplace of the fire-bars forming the bottom of the grate, said platecomprising four sectionsof equal size and shape and four filling-inpieces to fit between said sections, and a hollow coneshaped gridadapted to be placed on the top of said perforated plate above theopening therein.
